orinrnsvnnvn CONTROL.

Application filed November To all whom it may concern i Be it known that I, Jenn EDWARD l/Vns'r, a citizen of the United States, residing at Fortescue, in the county of Holt and State ofMiss'ouri, have invented certain new and useful Improvements in Chute-Valve Control, of which thefollowing is a specification, reference being had to the acconipany- This invention relates to certain improvements in grain elevators, and has relation more particularly to a devlce of this general character wherein a verticalmovable valve. or gate isemployed to control the flow over a chute leading from the grain bin to the boot of the elevator, and "itis an object of the invention to provide a novel 'and improved means whereby the gate or valve may be conveniently-and effectively locked in its different positions; v

"Another object to theinvention isto provide a gate or valve for the grain chute provided with an upstanding gateor operating valve, and with which coacts a novel and improved locking means embodying a holding member constantly urged in a direction for working engagement with the rod, together with means for moving the holding member away from the rod so that the gate or valve may be ad usted without mterfer once by said holding member.

Another ob ect of the invention 18 to provide a novel and improved mechanism coacty ing with the valve or operating rod for looking the valve or gate in desired position, together with means carried by the rod for limitingthe upward or opening movement of the valve or gate.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved grain elevator whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with-reference to the accompanying drawings, wherein: a

elevators, and illustrating an embodiment of 'my invention, as herein disclosed;

Figure 2 is an enlarged fragmentary view partly 1n elevation, illustratlng 1n detall my improved holding means coacting with the V denotes a verticallymovable valveor gate for controlling the flow of the grain from the bin G over the chute and extending upwardly from theyalve orgate Vis the rod R. The upperrend of tharod R is' providedwith a hand hold H whereby the rodR may be manually operatedto vertically move thevalve or gate V in accordance with the requirements of practice.

1 denotes a casing provided at its top with laterally directed flanges 2, whereby the casing can be readily anchored to the upper surface of the flooring F. The upper and lower walls of the casing 1 are provided with the vertically aligned openings 3 through which the rod R is directed, and whereby said rod R vertically intersects the casing 1.

Pivotally supported, as atr5, within the casing and to one side of the rod R is a holding or looking dog D, which has swinging movement toward or from the rod R and or edge of said dog D is provided with a groove 6 to receive the'rod B when the dog D is in looking engagement with said rod. The wall of the groove 6 is provided with the recesses 7 or the like, whereby the gripping action of the dog upon the rod R-is materially facilitated.

The dog D is constantly urged downwardly toward the rod B through the medium of the spring 9, and said sprin is of suflicient tension to lock the rod it normally against movement so that the valve or gate V may be eflieotively locked in its difierent is a plan view of the lock c a chute C delivering tothe positions as the requirements oi? pirmri'icc may necessitate.

The pivoted portion oi the dog I) is provided with the tail 1,0 with which contacts the lower end oi a vertically disposed. shank or releasing member 12. The member 12 extends upwardly throi'igh an opening ll; in the top of the casing 1, and through an opening 15 in the flooring F and in register withsaid opening let. The shank or release member 12has-itsupper end terminating a desired distance above-the flooring F, and is provided with-the head 16. Upon depression of the shank or release member 12, which may be accomplished by a: foot or otherwise, the dog D will be swung about its pivot in a direction away from the rod B so that desired endwise movement may be imparted to the rod R to obtain the d-sired positioning of the valve or gate V. Jpon relieving the shank or member 12 of pressure, the spring 9 will cause the dog D to automaticallygrip and lock the rod R. It

'is to be understood that the spring 9 is also of sufiicient tension to readily overcome the weightv of the shank or release member 12. v

Carrie d 'by the rod R at a desired point below the casing 1 is' a stop member M, which by engagement with the casing 1, serves to limit the upward movement of the valve or gate V, u so that displacement of said valve or gate V with respect to the chute C is prevented; 7

As herein disclosed the member M comprises two duplicate parts 16, having their central portions 17 provided with outloows adapted to embrace the rod R, and said parts 16 are clamped to the rod ll through the medium of the holts if; or the like. in order to increase the gripping :n-tion oi" the ports '16 upon the rod it. tho innrr or contacting 'i'ace ol the outhovvs l? are grooved or otherwise rmigg lirnod, as at 15).

From the foregoing dcsrripiion it is thought to he obvious that a grain elevator constructed in aurordanre with my invent ion. is particularly well adapted l'ornso h v rca-- son of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, andv for this reason i do not wish to he understood as limiting myself to the precise arrangement and format ion of the several parts herein shown in carrying out my invention in practice except as heroinafter claimed.

1 claim:

A chute valve control comprising a casing, a valve operating rod mounted to reciprocate vertically therein, a locking dog pivoted in the casing and having a, serrated cam-shaped rod engaging face, a spring normally acting to force the dog into locking engagement with the rod, and a vertically movable plunger slidahly mounted. in the casing and adapted to release the locking dog, said dog being adapted to loch the rod in any :nljustahle position, together with means to prevent displacement; of the valve.

In testimony whereof I hereunto afiix my signature.

JOHN EDWARD WEST.
